Ph.D., City University of New York (1996)

I teach all sorts of courses in physics, from introductory mechanics to advanced electives, and enjoy them all. I have developed a new course in Quantum Information that I have taught twice. As a former journalist, I am particularly interested in teaching my students how to write. I've taught our Intermediate Laboratory course in which students work on their writing in weekly lab reports.

Single molecule magnets, which are a few nanometers in size, are some of the smallest bistable magnets. How a magnetic particle reverses its orientation is a question of both fundamental interest and practical importance (e.g. for data storage in hard drives). These magnets can reverse their magnetic moment through a process that involves tunneling through an energy barrier that separates the up and down orientations of the magnet. We are doing several experiments to understand and control the reversal process. For example, we use microwaves to induce macroscopic changes in the magnetization.
I'm also starting up a research project to study the macroscopic quantum behavior of SQUIDs (Superconducting Quantum Interference Devices). These devices are superconducting rings in which the electrons “condense” to act as one collective object. This condensate can be put into a macroscopic superposition state in which billions of electrons “flow both ways at once”, an effect demonstrated by an experiment I did several years ago. In a new set of experiments, we will design and build some novel SQUID devices to explore new quantum effects and to try to understand how these systems lose their “quantumness” to eventually behave like most macroscopic objects, that is, classiscally.
